Household textile with effect of expelling bedbug and processing method thereof

ABSTRACT

The present invention relates to a household textile with effect of expelling bedbug, medicaments for expelling bedbug containing various extracts of natural plant are prepared, and textile shell fabric is passed through the medicaments for expelling bedbug at a certain speed with oven drying under certain temperature subsequently. The textile of the present invention can expel bedbug rapidly with characteristics of safety, environmental protection, and washing resistance, and the processing technology thereof is simple, and suitable for large-scale production.

TECHNICAL FIELD

The present invention relates to textile field, in particular to ahousehold textile with effect of expelling bedbug obtained by addingplant extracts medicament.

BACKGROUND ART

Mosquito is one of the factors disturbing work and rest of people,expelling of mosquito is always extensively concerned by people,products such as mosquito-repellent incense, floral water for expellingmosquito, and paster for expelling mosquito have been come out insuccession. How to give textile effect of expelling mosquito isconcerned by many researchers. Two main methods for the prevention ofmosquito are applied more maturely. The first method is a method tocarry out expelling or killing to mosquito existing in the environment,however, this method is not durable and medicament released from aerosolmay produce certain harm to human body, therefore, it is not suitablefor regular use. The second method is to carry out processing andfinishing to textile contacting with human body regularly, make it havemore durable effect of preventing mosquito. This method has been provedthat it has better effect of preventing mosquito through productionpractice for long time, and the product produced by the method is highlyresistant to washing without toxicity and harm to human body.

Bedbug is a kind of global pest, however, textile for expelling mosquitoand preventing insect exist in prior art has no or slight effect tobedbug expelling, and research in respect of textile specialised inexpelling bedbug has not been reported.

SUMMARY OF THE INVENTION

In order to overcome differences existing in prior art, the objects ofthe present invention is to utilize different natural plant extractcomprehensively and provide a kind of safe and household textile withdurable effect of expelling bedbug.

In order to achieve described objects of the invention, the technicalsolution of the present invention is:

A household textile with effect of expelling bedbug, it is characterisedin that the household textile is oven dried after dipping evenly withmedicament for expelling bedbug, the medicament for expelling bedbug ismade up of eucalyptus extract, peach leaf extract, melia azedarachextract, mint extract, fructus cnidii extract, clove extract, lavenderextract, folium artemisiae argyi extract, stabiliser and water.

Preferably, in the medicament for expelling bedbug, eucalyptus extractaccounts for 0.1-15 wt % of the total medicament for expelling bedbug,peach leaf extract accounts for 0.1-20 wt % of the total medicament forexpelling bedbug, melia azedarach extract accounts for 0.1-10 wt % ofthe total medicament for expelling bedbug, mint extract accounts for0.1-5 wt % of the total medicament for expelling bedbug, fructus cnidiiextract accounts for 0.1-5 wt % of the total medicament for expellingbedbug, clove extract accounts for 0.1-5 wt % of the total medicamentfor expelling bedbug, lavender extract accounts for 0.1-5 wt % of thetotal medicament for expelling bedbug, folium artemisiae argyi extractaccounts for 0.1-5 wt % of the total medicament for expelling bedbug,stabiliser accounts for 0.1-0.5 wt %, and water is the rest.

Preferably, the stabilisers of the medicament for expelling bedbug areone or more kinds of UV-P, UV-326, UV-531 and UVP-327.

Preferably, the water is clean river water or tap water; morepreferably, tap water.

The extract in the medicament for expelling bedbug is ethanol extract,preferably, extract is solid or concentrated solution, the concentrationof the preferable concentrated solution is greater than 90%.

The extract can be commercially available, for instance, the extractsold by Xi'an Yuensun Biological Technology Company.

The extract in the medicament for expelling bedbug can be prepared byconventional method, for instance, obtained by the following preparationmethods: taking folium eucalypti coarse powder 1 kg, using 5-fold amountof ethanol to soak for 3 times, merging the soak solution, obtainingconcentrated solution of ethanol extract through concentration underreduced pressure, or obtaining solid folium eucalypti extract by vacuumdrying the soak solution.

On the other hand, the present invention provides a method forpreparation of described household textile with effect of expellingbedbug, specific steps are as follows:

-   -   (1) Preparing the medicament for expelling bedbug;    -   (2) Soaking the shell fabric into medicament, bath ratio is        1:20, padding for two times, and the padding ratio is 80%;    -   (3) Oven drying the shell fabric processed with medicament for        expelling bedbug through oven of 100° C. at 10-60 m/min.

ADVANTAGEOUS EFFECTS

In the present invention, eucalyptus extract, peach leaf extract, meliaazedarach extract, mint extract, fructus cnidii extract, clove extract,lavender extract, and folium artemisiae argyi extract are screened outas effective components for expelling bedbug for characteristics ofbedbugs, and compounded to process household textile. Synergisticinteraction effect is significantly generated comparing with processingby utilising described extracts separately, bedbug can be expelledeffectively, meanwhile, plant extract is enable to promote human healthto a certain extent, and make the textile provide more effectiveprotection to human body.

Textile shell fabric processed by using described method, medicament forexpelling bedbug is formed a layer of film on the surface of fibre, withsmell hated by bedbug, and a kind of interference information isgenerated when contacting bedbug to achieve the object of expellinginsects. The effective components for expelling bedbug is enable topenetrate into the inside of fibre with fixed combination, when theeffective components on the surface of fibre are losing continuously dueto daily use and washing, the effective components in the fibre willmigrate to the surface continuously, thereby, ensuring that a certainconcentration of the effective components on the surface of fibre can bemaintained, therefore, household textile of the present invention ishighly resistant to washing, a certain insecticidal efficacy can stillbe maintained after washing for several times, and the efficacy can bemaintained for more than one year.

Specific shell fabric with passing speed and oven drying temperature areapplied by the processing method of shell fabric provided by the presentinvention, which not only makes effective components for expellingbedbug combined with the fabric fibre better, but also prevents too fastdegradation of the effective components. On the other hand, the ovendrying temperature of the present invention is lower, and it furtherguarantees that the effective components will not be damaged.
